New documents from the FBI quote a former State Department security official who said Secretary of State Hillary Clinton “blatantly” disregarded security and diplomatic protocols, frequently insulting and embarrassing U.S. ambassadors, and causing significant security headaches.

In particular, the agent, who was part of the State Department’s Bureau of Diplomatic Security, said Clinton routinely refused to ride in armored limousines with U.S. ambassadors, “instead choosing to be accompanied by her Chief of Staff, Human Abedin.”

“This frequently resulted in complaints by ambassadors who were insulted and embarrassed by this breach of protocol,” explained the FBI source, as quoted by the UK Daily Mail.

The agent described Abedin, who was technically Clinton’s Deputy Chief of Staff, as holding “much more power” over the Secretary of State’s staff and schedule than previous occupants of the position. In fact, the source believed “Abedin herself was often responsible for overriding security and diplomatic protocols on behalf of Clinton.”

The security officer also complained that Clinton used her secretary of state position to kickstart her presidential campaign, traveling with “hand-picked media who would present her in favorable light in order to garner political support,” and sometimes violating security protocols to get photo ops.

According to this source, Clinton sometimes overruled security recommendations for political purposes, which jeopardized her safety — along with that of her staff, media, and security detail.

The New York Postadds that these FBI interviews revealed that State Department security personnel “so disliked Hillary Clinton that many left the agency or asked to be reassigned.”

This testimony came from the same source mentioned by the UK Daily Mail. The agent “explained that Clinton’s treatment of DS agents on her protective detail was so contemptuous that many of them sought reassignment or employment elsewhere.”

“Prior to Clinton’s tenure, being an agent on the Secretary of State’s protective detail was seen as an honor and privilege reserved for senior agents. However, by the end of Clinton’s tenure, it was staffed largely with new agents because it was difficult to find senior agents willing to work for her,” the source claimed, adding that Secret Service agents also complained about working with Mrs. Clinton.
